11.7.2.1 Reading out the DP station list
Whenever the cyclic data exchange is disturbed with at least one DP slave
station, the DP station list can be read out with the HDB call RECEIVE
A-NR: 202.
If there is no fault/error, i.e. all DP slave stations are in the cyclic data
transfer phase, the HDB RECEIVE 202 call is blocked with the ANZW bit
"Receive possible".
